Re: Re: Structure

Ok cool thanks for that, so what if I add this code

  foreach my $req (@$reqs) {
    print "Registering '".$req->url."'\n";
    if ( my $res = $pua->register ($req) ) {
      print STDERR $res->error_as_HTML;
    }
  }
  $entries = $pua->wait();

  foreach (keys %$entries) {
    my $res = $entries->{$_}->response;
  }

Can someone explain to me what the %entries is all about...?

I want to loop through the above code lots and lots of time, but I need to clear out the entries hash after each run, how can I do this...?

undef %entries # or
%entries=();
[download]

Doesn't seem to work for me

Thanks again,
Tom

Can someone explain to me what the %entries is all about...? There is no hash %entries. There's only a scalar variable named $entries that seems to get back a hashreference as a result of the call `$pua->wait()` (whatever that is??). Read up on the differences between references and normal data types, e.g. in `perldoc perlreftut` or the same here online. When you say that you want to loop through the above code, what do you mean with above code? All of it? Because I see no reason why you should then need to clear out entries, you are getting back a new one every time out of `$pua->wait()` ... -- Hofmator	[reply] [d/l] [select]

Thanks, i've read the tutorial you told me about and it really helped, I didn't know anything about references, but now I do things are much easier, so thanks, I added the code `undef %$entries;` [download] Then ran my program and everything worked ok, the hash reference (or whatever) is cleared out after each loop and all works well! ... so far anyway!
